A certain pain-reliever is supposed to deliver 70 minutes of pain relief when given to a 150-160 lbs patient. A patient claims that the medicine on average provides a relief time that is less than 70 minutes per take. A simple random sample of 38 patients has the average and the standard deviation respectively 69.8 minutes and 5.98 minutes. Verify the assumptions in One Mean Z Hypothesis Test for testing the patient's claim assuming that the population standard deviation of pain-relieving times is 6 minutes.
